Horizon-Boundary Localization of the Hawking Temperature in a Weak AdS/CFT Extension
Wen-Xiang Chen, M. Zeeshan Gul
We establish a conditional boundary-localization statement for the Hawking temperature. For a static, Euclideanizable black hole with a non-degenerate horizon, the temperature is d…
Canonical-Ensemble Stability of the Quantum Oppenheimer-Snyder Black-Hole Exterior
Wen-Xiang Chen
We study the local canonical thermodynamics of the quantum Oppenheimer--Snyder (qOS) black-hole exterior previously obtained from loop quantum cosmology. The spacetime is adopted f…
Thermodynamic Consistency of Logarithmic Entropy Corrections on the Schwarzschild Branch of Gravity and a Superradiance No-Go Result
Wen-Xiang Chen
We present a concise and explicit analysis of logarithmically corrected black-hole thermodynamics and scalar scattering on the Schwarzschild branch of symmetric teleparallel gravit…
Hawking Temperatures of Dynamical Black Holes from the RVB--Residue Method:Vaidya and Kinnersley Geometries
Wen-Xiang Chen
This paper develops a local residue-based extension of the Robson--Villari--Biancalana method for calculating Hawking temperatures of dynamical black holes. Since non-stationary bl…
Dirac-Field Black Hole Entropy in \(f(Q)\) Gravity from the RVB Residue Method
Wen-Xiang Chen
We compute the entropy of a Dirac quantum field near a static, spherically symmetric black hole in (f(Q)) gravity by combining the residue-based Robson--Villari--Biancalana method…
Black Hole Entropy in f(Q) Gravity from the RVB Residue Method
Wen-Xiang Chen
We extend the residue-based Robson-Villari-Biancalana (RVB) method from the calculation of Hawking temperature to the determination of black hole entropy within f(Q) gravity. Start…
Non-Equilibrium Physics of Thermodynamicized Black Holes
Wen-Xiang Chen
This work presents a non-equilibrium framework for thermodynamicized black holes, inspired by the entropy-functional interpretation of emergent gravity and by residue-based methods…
Canonical and Grand-Canonical Singular Ensembles within a Thermodynamicized Gravity Framework
Wen-Xiang Chen
This paper develops a gravitational-thermodynamic interpretation of two ensemble structures with singular behavior, denoted as canonical ensemble A and grand canonical ensemble B.…
Threshold Temperature for Neutron-Star Emergence in a Gravitational Thermodynamic Framework
Wen-Xiang Chen
Motivated by the entropy-functional formulation of emergent gravity, in which spacetime is endowed with a thermodynamic entropy that, upon extremization, yields the Einstein field…
Energy Layers and Quasi-Superradiant Heat Engines of Schwarzschild Black Holes
Wen-Xiang Chen
We examine Schwarzschild black holes within the framework of gravitational thermodynamics, introducing an ``energy layer'' picture for black-hole mass-energy and exploring a possib…
Topological Complex Analysis of Kerr--Newman Black Hole Microstructure in f(R) Gravity
Wen-Xiang Chen
We investigate the microstructure of Kerr Newman black holes in modified gravity of the f(R) type using a topological complex analytic framework inspired by holography. In this app…
Topological and Geometric Properties of Spherically Symmetric Black Hole Metrics: Connections to Bose-Einstein Condensation and Uniqueness in Einstein Gravity
Wen-Xiang Chen
This paper investigates the interplay between the geometric and topological properties of spherically symmetric black hole metrics within Einstein gravity, emphasizing implications…
